  • 多能工作為生產管理經典的研究議題,除了物料規劃、需求管理及生產現場如何分配與安排,企業執行一個好的產能規劃必須搭配多能工進行有效率的生產,在高度客製化的商品中保有市場競爭力,這也促使多年來產官學界對產能規劃議題之研究蓬勃發展,以因應當代需求多變、產品複雜化等產業環境與銷售型態。產能規劃涵蓋內容甚多,其中粗略產能規劃(Rough-cut capacity planning, RCCP)主要針對企業接收到的新訂單做負荷規劃,不僅可以幫助管理者進行資源分配,也可以輔助其快速做出相對應的決策。
    本研究以一家變壓器製造商為案例對象,內容主要包含兩大部分。其一,善用該公司既有的資訊架構與數據,建置人員技能評估系統。相較於傳統的產能規劃議題,本研究特色為規劃時便將員工技能納入現場訂單工作的考量,因現場狀況通常是作業人員的工作負荷失衡,部分人員負擔過重,部分人員閒置,資源本身並未妥善利用,故本研究將提出改善,同時也包含如工時計算、生產線平衡等,跟以往既定平台或商業軟體之限制相比較為彈性;其二,針對現場人員進行負荷分配,根據其本身掌握的技能給予調整,並使用現況與另一情境實驗進一步分析改善情況與原因。
    實證研究中,實際建構出符合產業客製化需求的人員技能評估系統,就績效而言,安排今日生產訂單所花費的時間提高89%的效益;就線平衡率而言,由原先的25%提高至45%,改善成效達20%;技能利用率則是從42%變成70%,將技能利用率提高28%。

    The study of production management is a classic research topic that encompasses various aspects. In addition to material planning, demand management, and how to allocate and arrange production on the shop floor, companies need to implement effective capacity planning in order to maintain market competitiveness in highly customized products. This has led to the flourishing development of research in the field of capacity planning by industry, government, and academia over the years, in response to the ever-changing demands, product complexity, and sales patterns in the industry. Capacity planning covers a wide range of content, and one of its main components is Rough-Cut Capacity Planning (RCCP), which primarily focuses on load planning for new orders received by the company. RCCP not only assists managers in resource allocation but also facilitates them in making corresponding decisions quickly.
    This research focuses on a case study of a transformer manufacturer and consists of two main parts. Firstly, it involves leveraging the existing information structure and data of the company to establish a personnel skills assessment system. Unlike traditional capacity planning approaches, this study emphasizes incorporating employee skills into the consideration of on-site order skills. Since the workload of operational staff is often unbalanced, with some shouldering excessive burdens while others remain idle, the resources are not properly utilized. Therefore, this research aims to propose improvements, including factors such as processing time calculation and production line balancing. Compared to established platforms or commercial software, this approach offers more flexibility.
    The second part involves load distribution among on-site personnel, adjusting it based on their skills. The study also conducts situational experiments to analyze and improve the current conditions, as well as to identify the underlying reasons for any issues.
    In the empirical study, a personnel skills assessment system that aligns with the customized demands of the industry was successfully constructed. In terms of performance, the time required to allocate today's production orders improved by 89%. Regarding line balancing, the rate increased from the initial 25% to 45%, resulting in a 20% improvement. Furthermore, the skill utilization rate increased from 42% to 70%, marking a 28% enhancement in skill utilization.
